JavaWeb_(Spring框架)Spring整合Hibernate

　　Dao层类要继承HibernateDaoSupport.java父类

　　原先使用Hibernate框架hibernate.cfg.xml配置数据库

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql:///spring</property>

applicationContext.xml

　　在Dao层用到Session session = HibernateUtils.getCurrentSession()；获得session可以修改成

Session session = getHibernateTemplate().getSessionFactory().getCurrentSession();

　　在Service层用到的关于事务的开启我们可以统一在applicationContext.xml中进行配置

　　开启事务Transaction beginTransaction = HibernateUtils.getCurrentSession().beginTransaction();

　　事务回滚beginTransaction.rollback();

　　提交事务beginTransaction.commit();

　　在applicationContext.xml中配置事务核心管理器

<!-- 事务的核心管理器 -->
    <bean name="transactionManager"
        class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <!-- 需要sessionFactory -->
        <property name="sessionFactory" ref="sessionFactory"></property>
